PrefixTreeCell (Apache HBase - Prefix Tree 1.7.1 API)

java.lang.Object
- org.apache.hadoop.hbase.codec.prefixtree.decode.PrefixTreeCell

All Implemented Interfaces:

Comparable<Cell>, Cell, SettableSequenceId

Direct Known Subclasses:

PrefixTreeArrayScanner
```
@InterfaceAudience.Private
public class PrefixTreeCell
extends Object
implements Cell, SettableSequenceId, Comparable<Cell>
```
As the PrefixTreeArrayScanner moves through the tree bytes, it changes the values in the fields of this class so that Cell logic can be applied, but without allocating new memory for every Cell iterated through.
